I don't mind the "relevent" questions. But I've came across a couple that got a bit more personal then I like. Example: What is your morning routine? That's nobody's business unless I am late to work.
I do however, hate the "how would you manage this project" question, as my skill niche IS project management, and I have to really reign in my impluse to be overly verbose when I see that question.
As long as there was at least $1 paid on the contract it should show in your Work History. If it was an hourly contract, it will not show until the first payment is made. Also note that it may take up to 12 hours for your profile to update and display the new contract.
I hope it helps.
They are most irelevant when there is literally one sentence job description like "I need a mechanical engineer" and an additional question "what is most challenging part of this project?"....
I do it simple when relevant - either coping some portion from cover letter just to highlight things or adding couple sentences or even using that portion to ask some questions to the client in order to clarify things.
On my experience here it was just one time when I had to write bit more since potential client was asking a very specific questions (the type of technical questions you normally do not put in the cover letter body). I really was pleased to communicate with such a client.
In general I agree with idea that that there is a portfolio, there is a cover letter, there are feedbacks and history and if clienf is serious about the posted job and selecting right freelancer he/she should give more time to go deeper into freelancers profile. $5 - $10 "clients" of course do not do that.
Oh, just paid attention when the topic was opened....
